DISTRIBUTOR FOR POWDER BODY CONVEYED BY AIR FLOW AND DISTRIBUTION METHOD

PROBLEM TO BE SOLVED: To provide a distributor for powder body conveyed by air flow for achieving high reliability of distribution action even in high-pressure pressurized conditions and performing highly uniform distribution stably over a long time period. SOLUTION: The distributor 1 for powder body conveyed by air flow is formed so that a flow inlet for powder body 36 conveyed by air flow is formed at one edge while a conical space part 37 tapering off to the flow inlet side is arranged along the center axis. The distributor 1 includes a distribution part 31, a gas supply port 33 supplying distribution gas 32 to the distribution part, and a plurality of distribution discharge ports 34 delivering the powder body conveyed by air flow distributed in the distribution part to each of a plurality of distribution lines. Supply of the distribution gas by the distributing gas supply port is carried out in a jet flow condition so that swirl flow 40 turning along the center axis of the distribution part to generate a negative pressure area 39 in the center occurs in the distribution gas.
